Description

清潔劑組合物Detergent composition

本發明係關於一種清潔劑組合物及該清潔劑組合物所使用之清潔用界面活性劑。本發明尤其是關於一種餐具用清潔劑組合物及該餐具用清潔劑組合物所使用之餐具清潔用界面活性劑。The present invention relates to a detergent composition and a cleaning surfactant used in the detergent composition. The present invention particularly relates to a detergent composition for tableware and a surfactant for tableware cleaning used in the detergent composition for tableware.

去除硬質表面上之油污係對硬質表面清潔劑強烈要求之性能之一。特別是疏水性表面上之油污難以清除,清潔劑之使用者為了將其清除,會使用極大之機械力、利用溫水、添加清潔劑等。為了減少對使用者或環境之負荷,亦正尋求以更低機械力之清潔、於更低溫下之清潔、綜合性之活性劑之排出量能夠進一步減少之界面活性劑、或清潔劑之開發。 相對於此,已知有於烷基鏈上具有支鏈之界面活性劑、或含有該界面活性劑之清潔劑(例如專利文獻1~3)。 專利文獻1(日本專利特表2013-532736號公報)以冷硬水中之油脂(grease)去除為課題,揭示有一種鏈末端附近分支型化合物及該等之衍生物之新穎混合物、及含有該等混合物之清潔組合物。 專利文獻2(日本專利特開2013-100461號公報)以提供在相對較低之溫度下兼顧對強力地附著於具有疏水性表面之餐具類或烹飪器具等之油污即液體油及固體油脂之清潔力的手洗用餐具清潔劑為課題,揭示有一種以特定量比使用有磺基琥珀酸烷基酯或其鹽、特定之陰離子界面活性劑、磺基甜菜鹼型界面活性劑的手洗用餐具清潔劑組合物。 專利文獻3(日本專利特表2000-503700號公報)以較低之使用溫度下之清潔力、或耐硬水性為課題,揭示有一種至少包含烷基長鏈中長鏈分支界面活性劑化合物0.5重量%之洗劑界面活性劑組合物。Removal of oil stains on hard surfaces is one of the performances that are strongly required by hard surface cleaners. Especially the oil stains on the hydrophobic surface are difficult to remove. In order to remove it, the user of the cleaning agent will use great mechanical force, use warm water, add cleaning agent, etc. In order to reduce the load on the user or the environment, it is also seeking to develop surfactants or detergents that can be further reduced by cleaning with lower mechanical force, cleaning at a lower temperature, and comprehensively reducing the discharge of active agents. On the other hand, surfactants having a branch in the alkyl chain or detergents containing the surfactant are known (for example, Patent Documents 1 to 3). Patent Document 1 (Japanese Patent Publication No. 2013-532736) focuses on the removal of grease in cold and hard water, and discloses a novel mixture of branched compounds near the chain ends and these derivatives, and containing these The cleansing composition of the mixture. Patent Document 2 (Japanese Patent Laid-Open No. 2013-100461) provides cleaning of liquid oil and solid grease that is strongly adhered to tableware or cooking utensils with hydrophobic surfaces at a relatively low temperature. A strong handwashing dishwashing agent is the subject, and it is revealed that there is a handwashing dishwashing that uses alkyl sulfosuccinate or its salt, specific anionic surfactants, and sulfobetaine surfactants in a specific amount剂组合物。 Agent composition. Patent Document 3 (Japanese Patent Publication No. 2000-503700) focuses on cleaning power at a lower use temperature or resistance to hard water, and discloses a surfactant compound containing at least a long alkyl chain, medium and long chain branched surfactant 0.5 Wt% lotion surfactant composition.

然而,就專利文獻1~3記載之清潔劑而言,於包含固體油脂之油污之清潔性中,尚不可言充分。 本發明係關於一種附著於塑膠等硬質物品之硬質表面尤其是餐具之包含固體油脂之油污之清潔力優異的清潔劑組合物及該清潔劑組合物所使用之清潔用界面活性劑。 對於該課題,本發明者等人發現:具有特定之分支結構之磺基琥珀酸型界面活性劑之包含固體油脂之油污之清潔性能優異。 即,本發明係關於一種清潔劑組合物,其含有下述通式(a1)所表示之界面活性劑作為(a)成分。 [化1]

Combine butter (Sigma-Aldrich Japan Co., Ltd.) and rapeseed oil (Kishida Chemical Co., Ltd.) at 9 :Mixed with a mass ratio of 1 as a model stain (model stains containing solid grease stains, the same as below). The quality of a 30 mm (horizontal) × 80 mm (vertical) × 1 mm (thickness) polypropylene test piece (manufactured by Engineering Test Service Co., Ltd.) was measured with a 4-digit balance (p). A stain piece is made by uniformly coating the model stains to a height of 50 mm from the lower end so that the total of both sides becomes 0.02 to 0.04 g on both sides of the above-mentioned polypropylene test piece. The quality of the stained piece was measured with a 4-digit balance (q). (2) Procedure of evaluation Add 50 g of each detergent composition described in Table 1 to a 50 mL container (cylindrical shape with an inner diameter of 35 mm × a height of 68 mm), and then place a stain piece in the container to make It is contacted with the composition described above. At this time, all the stained part of the stain member is immersed in the above composition in the container. After immersing the stained piece in the detergent composition in the container for 1 minute, the stained piece is taken out and rinsed with running water for 1 minute. At this time, the conditions for flushing with running water are: the temperature of tap water is 25°C, the flow rate is about 4 L/min, and the diameter of the opening of the faucet is about 15 mm. With respect to the tap water dripping to the stained piece 5 cm vertically downward from the opening, hold the stained piece at 45°, and use the upper end of the stained piece that is not stained while fixing the angle Part of it accepts running water, and the entire single side of the clean part is rinsed with tap water running on the stained part. At this time, the front and back sides are changed every 10 seconds and rinsed alternately. After rinsing, the stained piece is dried, and then the mass is measured with a 4-digit balance (r).
